Hi Andreas, Using the Intel IPP for echo cancellation is a tricky thing. You really have to know what you're doing, and although the IPP package gives you lots of primitives for creating your own AEC, they don't make any guarantees about whether you're infringing on someone's patent if you use them. If you're looking for an unencumbered AEC that you can pretty much drop-in, you should check out the AEC in the webrtc project. In my experiance it works much better than the speex AEC. --John On 8/26/2013 12:16 PM, pjsip-request at lists.pjsip.org wrote: > Send pjsip mailing list submissions to > pjsip at lists.pjsip.org > > To subscribe or unsubscribe via the World Wide Web, visit > http://lists.pjsip.org/mailman/listinfo/pjsip_lists.pjsip.org > or, via email, send a message with subject or body 'help' to > pjsip-request at lists.pjsip.org > > You can reach the person managing the list at > pjsip-owner at lists.pjsip.org > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of pjsip digest..." > > > Today's Topics: > > 1.
